EVC and Ethernet Service Types

Diagram 1

Private and Virtual Private Services

  • Each Service type supports both a Private and Virtual Private service definition

    • ALL to ONE BUNDLING - Creates Port based or Private Services

    • SERVICE MULTIPLEXING (more than one EVC on single UNI) and or BUNDLING (more than 1, but not ALL CE-VLAN ID's) are bundled to ONE EVC are VLAN aware or Virtual Private Services

Diagram 2

All to One Bundling

  • ALL customer traffic is bundled to ONE EVC

    • Can be untagged traffic, Priority tagged (CE-VLAN 0), or tagged (VLAN ID's between 1 & 4095)

  • ONE service is created on the UNI

  • All to One Bundling creates a PORT-BASED Service

  • All to One Bundling cannot be combined with VLAN-based Service Multiplexing or Bundling attributes (I like to think of "Bundling" as VLAN BUNDLING)

Diagram 3

Bundling (VLAN Bundling)

  • Multiple (more than one), but not all CE-VLAN IDs are bundled to one EVC

  • Bundling is a VLAN-based service attribute and can be used in conjunction with Service Multiplexing

Diagram 4

Service Multiplexing

  • Multiple Services on a Single UNI

    • Each service must have at least 1 CE-VLAN ID mapped to it

    • Bundling can be combined with service multiplexing where multiple CE-VLAN ID's can be bundled to each EVC

    • Service Multiplexing allows different EVC services (EVPL, EVP-LAN and EVP-Tree) to be delivered on a single UNI as long as they are ALL VLAN based services (see diagram 7)
